libltdl.so.3 is the name of the file you're wanting to get. You have to give yum package names to install to figure out what package provides a particular file:"yum whatprovides */libltdl.so.3"

you need to install the package "libtool-ltdl" not "libltdl.so.3" This is only a shared library that is a part of the package mentioned above.

yum install "libtool-ltdl"
rpm -Uvh ImageMagick-6.8.4-9.i386.rpm

should get it working.

Hi and thank you for your answer, however I've already tried that with the same outcome. I reinstalled the whole libtool-ltdl package but then, when trying to install the Image::Magick package, I get the dependencies issue.

what version is your copy of libtool-ltdl ? on rpm search it shows libltdl.so.3 in package CentOS 5 ftp.centos.org/5.9/os/x86_64/CentOS/libtool-ltdl-1.5.22-7.el5_4.x86_64.rpm as well as the same version for i386

My currently installed version is libtool-ltdl-2.2.6-15.5.el6.i686

have listed the packages that have it maybe you can install that specific version at the same time if you have other dependences that need it. Check to see if you have an older version of Image Magick.

A simple yum install ImageMagick should do (it is very unlikely that it was installed without the dependencies). If the system thinks the package is installed, yum reinstall ImageMagick is the command to run. If this gives trouble, yum deplist ... gives the list of packages providing dependencies.

Also install yum-utils, check at least the manual pages for yum and package-cleanup.
